The
CA18RLY driver is a descendent of classic drivers
like the Vifa C17WH and SEAS CA17RCY drivers. A
light-weight paper cone and 25 mm voice coil
makes an extended range driver with relatively
high sensitivity. This time we get a thoroughly
vented chassis and rubber surround and as
previously a smooth extended frequency response
up to 6 kHz , making crossover work easy.

The
22TAF/G tweeter is totally new. A 20 mm alu dome
with a wide fabric suspension combines some of
the qualities of small and large domes and
provides an extended response down to 1.5 kHz. An
easy driver too when it comes to crossovers.

System
sensitivity is 86-87 dB/2.8 volts and being an
easy load this speaker can be driven from almost
anything. Despite modest size it will throw a
significant soundstage and should you decide on a
24 liter cabinet, an extended bass response too.
Do not expect earth-quake scenarios from 135
square centimeter membrane area. Simple physics
apply to this construction too.

Several
options are available for the CA18RLY driver.
Should you want a compact monitor, 16 liter will
provide decent bass to around 60 Hz with +1 dB in
the lower region, where a 24 liter floorstander
makes F3 = 50 Hz (port = 50 (ID) x 80 mm. To get
the drivers into reasonable listening height, a 1
meter cabinet is recommended and surplus volume
at bottom of cabinet can be used for sand filling
and crossover.
